About Converting Grams per Imperial gallon to Grams per Cubic yard
Gram per Imperial gallon and Gram per Cubic yard both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
grams per cubic yard = grams per imperial gallon × 168.178557394
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per imperial gallon equals 0.219969248299 base units, and 1 gram per cubic yard equals 0.00130795061931 base units, so dividing one by the other gives the direct gram per imperial gallon-to-gram per cubic yard factor of 168.178557394.
Simple example
1 g/imp gal × 168.1785574 = 168.1785574 g/yd3
1 gram per imperial gallon = 168.1785574 grams per cubic yard.
Real-world example
1,000 g/imp gal × 168.1785574 = 168,178.5574 g/yd3
1,000 grams per imperial gallon = 168,178.5574 grams per cubic yard.
